Diatoms composing benthic microbial mats in freshwater lakes of Skarvsnes ice-free area, East Antarctica / Taisuke Ohtsuka, Sakae Kudoh, Satoshi Imura, Shuji Ohtani.

Title: Diatoms composing benthic microbial mats in freshwater lakes of Skarvsnes ice-free area, East Antarctica / Taisuke Ohtsuka, Sakae Kudoh, Satoshi Imura, Shuji Ohtani.
Author(s): Ohtsuka, Taisuke.

In: National Institute of Polar Research. Polar Bioscience. (2006.), Vol. 20 (2006)
Abstract: Discusses diatom species composing benthic microbial mats in terms of taxonomy and relationship to environmental factors. Amphora sp. was dominant in 11 of 13 samples, while Craticula sp. and Diadesmis sp. were respectively dominant in remaining two samples. Navicula ectoris Van de Vijver was also reported for first time in continental Antarctica. Mosses in microbial mats did not have significant effect on diatom species composition. Redundancy analysis showed that main environmental gradient for diatoms was electric conductivity, despite its relatively narrow range. Results suggest that Diadesmis sp. and Psammothidium metakryophilum are halophobes, whereas Amphora sp. is halophile.
